TitleLetter from Charles Algernon Parsons, C A Parsons and Company Limited, Heaton Works, Newcastle-on-Tyne, to [Dugald] Clerk
Date6 May 1915
DescriptionThe only information still required is the rate of vertical rise of the standard mine with 100lbs lifting force. He can start making as soon as this is known. Proposes to test the mine in a pressurized tank made from an egg-ended boiler with observation windows. As an afterthought, asks for an empty mine to be sent so that they may test the rate of rise at Wallsend, off their jetty.
